I was using my computer then all of the sudden my pc just started to restart itself when it tried to restart it got stuck on the loading screen and wouldn't go past it, so I had no choice but to turn off my computer and turn it back on, but on the reboot I got the first startup screen but then after a while it turned to a black screen with white text and it said "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key". After this happened I restarted my computer and ran the diagnostics, the cpu, RAM, and DvD drive passed except the hard drive, it said there was not a hard drive inserted and gave me the error BIOHD-2. After I saw this I called HP for support and I waited about 30 mins on hold and talking to the support agent giving him all the information he needed to find out that I have to pay $60 to get help from them. I was getting impatient after this and took my hard drive out of my pc, took all the dust off and plugged back in but while holding it in my hand to see if it would start up and everything, the good news is that it did so I knew tha wasn't the problem, but now I don't know what to do. I am seeking your help as you are my only hope. I am actually typing this from my Xbox because I have no other computers to test on which have SATA drives, and my computer model # is m8530f so you can look at what parts it has and help me solve this problem. Thanks in advance!
